If a rectangular field of an area 100 square units is divided into two parts of area 36 square units and 64 square units along the length such that the length of the original field and both the newly created fields are coprime to each other, then the sum of the length of original field and both the newly created fields is

Solution
100=22×52 64=26 36=22×32 Since, the common factor among all is 22 So, the breadth is 22=4 and the lengths are 100=4×25 64=4×16 36=4×9 So, sum is 25+16+9=50 units
